Arrhythmia & Cardiomyopathy

Persistent Atrial Fibrillation

Long-Standing Irregular Fast Heartbeat Leading to Weak Heart Function

Persistent Atrial Fibrillation (AF) is a condition where the heart beats irregularly and often rapidly for prolonged periods. When this fast rhythm persists, it can weaken the heart muscle over time, leading to tachycardia-induced cardiomyopathy and heart failure.

What is Persistent Atrial Fibrillation?

Irregular Rhythm

Atria beat rapidly

Persistent

Long-standing

Heart Weakens

Cardiomyopathy develops

Heart Failure

Progressive

Long-standing fast heart rate → Key reversible cause of cardiomyopathy

Early rhythm control can reverse heart damage.

Understanding

What is Persistent Atrial Fibrillation?

In persistent AF:

Upper chambers (atria) beat irregularly and rapidly
Heart rate remains uncontrolled for long periods

Over time:

Heart muscle weakens
Pumping ability declines

This leads to:

Cardiomyopathy
Heart failure
Increased stroke risk

Warning Signs

Early Signs & Symptoms

Palpitations

Early Stage

Breathlessness

Progressive

Leg Swelling

Advanced

Long-standing fast heart rate → Key reversible cause of cardiomyopathy

Risk Factors

Causes & Risk Factors

Causes

Persistent atrial fibrillation
Poor rate control

Risk Factors

Hypertension
Thyroid disorders
Alcohol use
Structural heart disease

Progression

Disease Progression

Early Stage Rapid irregular rhythm

Moderate Stage Reduced heart function

Severe Stage Cardiomyopathy develops

End Stage Transplant needed

Early Stage

Rapid irregular rhythm

Reversible with treatment

Rhythm Control

Moderate Stage

Reduced heart function

Medical Management

Severe Stage

Cardiomyopathy develops

Advanced Care

End Stage Heart Failure

Severe dysfunction

Transplant required

Heart Transplant

Testing

Diagnosis & Tests

ECG (confirms AF)

Holter monitoring

Echocardiography

Blood tests (thyroid, electrolytes)

Monitor irregular heart rhythm early

Assess your heart function risk

Management

Treatment Options (Before Transplant)

1. Rate Control

Beta-blockers
Calcium channel blockers

2. Rhythm Control

Anti-arrhythmic drugs
Electrical cardioversion

3. Catheter Ablation

Restores normal rhythm

4. Anticoagulation

Prevents stroke

When is Heart Transplant Needed?

Severe cardiomyopathy persists

Irreversible heart damage

Poor response to rhythm control

Early Treatment Can Reverse Heart Damage

Timely rhythm correction is critical

Important Consideration: Reversible Cause of Heart Failure

• Often reversible if treated early • Requires strict rhythm control • Delay leads to permanent damage

Medical/Ablation vs Transplant

Medical/Ablation Therapy

Stage: Early/Moderate • Goal: Restore rhythm • Outcome: Often reversible

Heart Transplant

Stage: Advanced • Goal: Replace heart • Outcome: Life-saving
